The strong midinfrared polaronic signal in p-doped polymers such as P3HT is analyzed in terms of a plasmonic absorption cross section. Quantitative conclusion on the hole mobility along chains of coherently connected thiophene units is derived in that way. This intrachain mobility is more than two orders of magnitude higher than average mobilities of doped polymers which is limited by the much less efficient interchain transport processes.

掺杂 P3HT 薄膜中等离子体极化子的红外光谱分析

根据等离子体吸收截面分析 p 掺杂聚合物（如 P3HT）中的强中红外极化子信号。以这种方式导出了沿着相干连接的噻吩单元链的空穴迁移率的定量结论。这种链内迁移率比掺杂聚合物的平均迁移率高两个数量级以上，而掺杂聚合物的平均迁移率受到链间传输过程效率低得多的限制。
